Streaming Data Portal

The Coweeta LTER uses the GCE LTER Data Toolbox and the Mathworks® Matlabcomputing environment to maintain a near-real-time sensor network for stations both within the Coweeta Hydrologic Laboratory and regionally within southern Appalachia. Links to these data sets are available below. GIS data and information can be found here in our GIS portal.For most of the streaming sensor stations, data from previous years can be found within the data catalog under the associated dataset ids listed in the sections below.

Soil Moisture, Soil Temperature, and Air Temperature Measurements from Sites Within the Coweeta Basin
Soil moisture is measured at sites within the Coweeta Basin across a range of elevations and watersheds. At each station, soil moisture is measured from depths of 0 -30 cm and 30-60 cm below the mineral soil surface. Soil temperature is measured at various depths along with air temperature measurements. At select stations, relative humidity and photosynthetically active radiation are measured. All measurements are taken and recorded at 5 minute intervals. Associated datasets: 1040Associated GIS files.

Soil Moisture, Soil Temperature, and Air Temperature Measurements from Southern Appalachia Regional Sites
Regional southern Appalachia soil moisture sites were established to compare measurements at various elevation, climate, and spatial scales. At each station, soil moisture is measured from depths of 0-30 cm and 30-60 cm below the mineral soil surface. Soil temperature is measured at various depths along with air temperature measurements. At select stations, relative humidity is also measured. All measurements are taken and recorded at either 5 minute intervals, or every 60 seconds with hourly minimum, maximum, and average values recorded.

Microclimate measurements from the Forest Gap Sites
Ten artificial Forest Gap Sites were created in March 2002 at Coweeta, following two years of pretreatment data collection. From 2000-2014 manual soil moisture measurements were taken and results can be found in dataset: 1113. In 2015, dataloggers were installed at each Forest Gap Site to continuously measure soil moisture, soil temperature, and at cetain gaps, air temperature. Measurements are taken every 60 seconds with hourly minimum, maximum, and average values recorded. Associated datasets: 11131114Associated GIS files.

Climate Measurements from the Southern Appalachia and Piedmont Regions
These weather stations provide climate based measurements from locations near ongoing Coweeta LTER research with most beyond the immediate boundaries of the Coweeta Hydrologic Laboratory. The Coweeta LTER maintains a high density of sites within the Upper Little Tennessee drainage as well as sites along broad-scale elevational and latitude gradients within and around the Southern Appalachia and Piedmont regions. Measurements are combinations of the following: air temperature, relative humidity, wind speed and direction, rainfall, and solar and photosynthetically available radiation. Measurements are taken every 60 seconds and output hourly for minimum, maximum, and average values. Hourly and floating 24 hour rainfall totals are calculated. The online streaming data covers only the current calendar year. Full station datasets through the previous years can be found in the data catalog.
